 You're currently long and in profit. Your trading plan states $42.30 as your target. But some choppy price action suggests bullish momentum is slowing. What do you do here? Take early profit, move your stop higher, or do nothing and let the trade play out. What about now? Does this help your decision? Bookmap shows a wall of resting sell orders stacking on the offer. Now, this isn't necessarily bad news for your long, but does provide additional insight to help make solid discretionary decisions. What's important here is how price, or aggressive buyers in this case, behave when faced with this sell side liquidity. They may just sweep through it into your target. But in this example, the liquidity appears to be absorbing buyers. In other words, there are currently no buyers willing to lift the offer in this area. So if your trading plan allows for discretionary decision making, it's time to at least take part your profit. Could you have made the same decision by looking at candlesticks alone? Take another look and imagine this scenario without bookmap.
